Key features of the Apple Watch Ultra 4
Grade 5 Titanium case: built for extreme conditions
The 49mm Grade 5 Titanium case uses 45% recycled titanium content and is designed to withstand conditions that standard Apple Watch models are not rated for. A raised edge protects the flat sapphire crystal display from direct impacts. The customizable Action Button provides one-press access to workouts, compass waypoints, or any assigned shortcut. An 86dB Emergency Siren can be heard from significant distances in outdoor emergencies.
S11 SiP: what the new chip enables
The Apple S11 SiP powers smoother performance across demanding apps, enables new single-handed gestures including Wrist Flick and Double Tap, and runs Live Translation and Siri AI via Apple Intelligence. The same chip is in the Apple Watch Series 12, but the Ultra 4 benefits from a larger thermal envelope that allows it to sustain peak workloads for longer.
Dual-Frequency GPS: precision where it matters
The Ultra 4 uses Precision Dual-Frequency GPS combining L1 and L5 bands. In practice, L5 provides significantly better accuracy in environments where GPS signals are reflected or obscured dense urban environments, canyons, and forest trails. The Series 12 uses L1 GPS only. For runners and outdoor athletes who train in mixed terrain, this is a meaningful accuracy advantage.
Emergency Siren and dive certification
The 86dB Emergency Siren is designed to attract attention if you are injured in a remote location. EN13319 dive certification means the Ultra 4 meets the international standard for recreational dive equipment and can be used for scuba diving to 40m something no other Apple Watch model is certified for.
New Health Sensing System explained
The Ultra 4 introduces an all-new Health Sensing System with larger, power-efficient green LEDs that measure heart rate continuously every 5 seconds throughout the day significantly more frequent than previous generations. This higher frequency powers several new and improved capabilities.
Readiness Score
A daily score from 0 to 10 that evaluates your current capacity to take on a workout versus prioritizing rest. It combines recent training load, vitals, and sleep data to give you a single actionable number each morning. Readiness Score is new to this generation and was not available on Ultra 3.
Recovery HRV tracking
Heart Rate Variability during recovery is now tracked up to 24 times more frequently than on the Ultra 3. HRV is a recognized indicator of training readiness and stress. More frequent measurement gives the watch more data to generate reliable Readiness scores and overnight vitals views.
Daytime and overnight vitals
Toggle easily between daytime and overnight metric views. Overnight vitals track heart rate, HRV, respiratory rate, and wrist temperature during sleep. Daytime vitals provide context across your waking hours. The combination helps spot early shifts in body state that might indicate illness, overtraining, or recovery.
Battery life: understanding the ratings
Apple publishes three battery ratings for the Ultra 4. These are separate tests, not interchangeable figures.
| Mode | Rated duration | What it represents |
|---|---|---|
| Everyday use | Up to 50 hours | Mixed usage including notifications, workouts, GPS sessions, and sleep tracking |
| Low Power Mode | Up to 84 hours | Reduced functionality mode for extending battery when needed |
| Outdoor workout tracking | Up to 45 hours | Continuous GPS and sensor recording during active outdoor exercise |
The 50-hour everyday rating is a meaningful improvement over the Ultra 3's 42 hours. For multi-day trips, hikes, or triathlons where charging is not available, the gap between 42 and 50 hours may determine whether you reach the end of an event with battery remaining.

| Feature | Apple Watch Ultra 3 | Apple Watch Ultra 4 |
|---|---|---|
| Chip | S10 | S11 SiP |
| Health Sensing System | Standard sensor array | New Health Sensing System (5-second continuous heart rate, Recovery HRV) |
| Readiness Score | Not available | Included (0–10 score) |
| Battery (everyday) | Up to 42 hours | Up to 50 hours |
| Battery (Low Power Mode) | Up to 72 hours | Up to 84 hours |
Ultra 3 owners should consider whether the new Health Sensing System, Readiness Score, and 8 additional hours of everyday battery life address specific needs in their training or health routine. For Ultra 2 or older users, the improvement in battery life, display visibility, and health metrics is more substantial.

What is the Readiness Score on Apple Watch Ultra 4?
A daily score from 0 to 10 that analyzes your recent training load, overnight vitals, and sleep to give you a single number reflecting your readiness to train or need to rest. It is powered by the new high-frequency Recovery HRV tracking and was not available on any previous Apple Watch model.
Is the Apple Watch Ultra 4 suitable for scuba diving?
Yes. The Ultra 4 carries EN13319 certification for recreational scuba diving to 40m and high-speed water sports. It includes a depth gauge accurate to 40m and a water temperature sensor. No other Apple Watch model is certified for scuba diving.
Does Apple Watch Ultra 4 support 5G in Saudi Arabia?
Yes. All Ultra 4 models include 5G RedCap cellular, compatible with 5G networks from STC, Mobily, and Zain in Saudi Arabia. Cellular requires a paired iPhone and a supported cellular plan from your carrier.
Should I upgrade from Apple Watch Ultra 3 to Ultra 4?
The decision depends on how much value the new Health Sensing System, Readiness Score, and 8 additional hours of everyday battery life add to your routine. For athletes who train extensively and would use high-frequency HRV tracking and the Readiness Score daily, the upgrade is meaningful. For casual users who primarily wear the Ultra for its size and battery, the Ultra 3 remains a strong performer.
